Houseplants
Mix one teaspoon per gallon of water and feed to the plants every two to four weeks

For vibrant plants and vegetables- like your body, plants will suffer if they lack nutrients. By adding just a spoonful of epsom salt you can prevent weak stalks and yellow leaves. Sprinkle epsom salt around the base of a plant will lead to big healthy vegetables.

Also, look for the one in the milk carton style container, not the dark glass jars (for ingestion, that is for taking internally, higher grade & more expensive).

I'd think twice abt doing this thru winterime when plants are slowing down in their growth. Or maybe just do it once thru winter, & somewhat more often in Spring & Summer.

Also, some caution here pls. follow the recommended doses, plants can be damaged from too much of this. Someone who was a frequent contributor here 'til recently, overused this somewhat & did damage to a number of her Sansevierias & alerted us to that fact.

I have been lurking and kibitzing on GW forums since 1997 and I am fascinated by the frequency with which "Epsom Salts" appears in the subject line. A GW search pulls up 765 hits and Googling GW finds a few more.

I have pondered this for about 10 years now and I can see no particular advantage other than Epsom Salts are a handy source of magnesium and sulfate. If one needs magnesium or sulfate then it should be a convenient source.
